IMPROVEMENT IN GLUING DEVICES.

Specification forming part of Letters Patent No. 149,706, dated April 14, 1874; applieation'liled September 20, 1873.

.To all whom it may concern:

Be it known that I, HIRAM BALDWIN, of

l Nashua, in the countyrof Hillsborough and part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is arepresentation of a vert-ical section of my gluing device. Fig.

2 is a transverse section of same. detail of same.

This invention relates to an improvement which is applicable to glue kettles or pans, and which is intended to facilitate the application of glue to the joints of boards in the manufacture of boxes and other articles. It consists in a rotary wheel or drum arranged so as to dip into the glue-pan, and to be easily turned by a crank, which drum presents grooved, prismatic, smooth, cylindrical, or other surfaces adapted to the kind of Work which is to be glued, as will be hereinafter explained.

` The following is a description of my improvement:

Fig. 3 is a In the accompanying drawings, A reprerepresents a gluing-drum, of any suitable dimounted in bearings e e on the end flanges of the pan D1, and has a hand-crank, e, ora beltpulley, applied to oneend of it, as shown in Fig. 1. By means of the crank e the drum D'l can be turned about its axis, and freshly-glued surfaces exposed above the surface of the glue in pan D1. The circumference of the drum DZ may present grooves and ridges, as indicated at a a, or it may present prismatie surfaces b,

or a smooth cylindrical surface, d. The rectangular grooves and ribs a are designed for applying glue to the ends of boards which are notched -as indicated by Fig. 3, the tongues and notches of which correspond to, but are slightly smaller than, the grooves and ridges a on the drum D2. adapted for applying glue to the flat surfaces of the bottoms of boxes, and the smooth cylindrical surface d is intended for applying glue to the ends of boards.

It is obvious that by rotating the drum D2 freshly-glued surfaces can be exposed, from which the glue can be applied to any object by simply laying the same on such surfaces. I thus greatly facilitate the gluing of boxes and other articles.

What Iclaim as new, and desire to secure by Letters Patent, is-

The gluingl apparatus described, consisting of the furnace B, pans D and D1, and cylinder D2, all arranged and operating as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

HIBAM BALDWIN.
